"Nartok shows me an example of Arctic "greens": cutout number 13, Caribou Stomach Contents. Moss and lichen are tough to digest, unless, like caribou, you have a multichambered stomach in which to ferment them. So the Inuit let the caribou have a go at it first. I thought of Pat Moeller and what he'd said about wild dogs and other predators eating the stomachs and stomach contents of their prey first. "And wouldn't we all," he'd said, "be better off." If we could strip away the influences of modern Western culture and media and the high-fructose, high-salt temptations of the junk-food sellers, would we all be eating like Inuit elders, instinctively gravitating to the most healthful, nutrient-diverse foods? Perhaps. It's hard to say. There is a famous study from the 1930s involving a group of orphanage babies who, at mealtimes, were presented with a smorgasbord of thirty-four whole, healthy foods. Nothing was processed or prepared beyond mincing or mashing. Among the more standard offerings--fresh fruits and vegetables, eggs, milk, chicken, beef--the researcher, Clara Davis, included liver, kidney, brains, sweetbreads, and bone marrow. The babies shunned liver and kidney (as well as all ten vegetables, haddock, and pineapple), but brains and sweetbreads did not turn up among the low-preference foods she listed. And the most popular item of all? Bone marrow."
